Thin section ball bearings

The major characterizations of the FRB BEARINGS thin-section ball bearing are that, light weight, sufficient rigidity, small section, and the excellent load bearing performance. They also have many kinds of sections and dimensions. As usual we called it as Thin-section ball bearing when the hole diameter was more than 4 times larger than the radial sections. It can solve many design problems which the common bearings cannot complete in application. The Thin-section ball bearings produced by our FRB BEARINGS company totally have three kinds of structural, are divided into five series. Among them, the sections which change with the hole diameter are two times of the steel balls’ diameter ..The diameter unit usually is inch.

The thin-section ball bearings series FRB BEARINGS are always used in the circumstances, such as requiring small space, heavy load ,light weight or limiting some special forms .At the same time ,we also provide some special services ,for example ,we produce bearings according to the customers’ blueprint re. At present ,each series of them are widely applied in aircraft ,aerospace and astronomy instrumentation, fixing and work holding equipment ,food processing equipment ,glass working equipment ,index and rotary tables ,packing equipment ,machine tools ,medical devices ,optical scanning equipment ,radar, satellite and communications equipment ,robotics ,textile machinery ,tube and pipe cutting machines, semiconductor manufacturing equipment ,sorting equipment and so on in all the various trades and occupations.

Depending on the application, Thin Ball bearings are divided into five types:

1.Open Radial Contact Ball Bearing (KA, KB, KC, KD, KF, KG series)
Thin-section radial contact ball bearing primarily designed for deep groove ball bearing to sustain heavy pressure. The basic design intention is not only to support radical load, but also can sustain middle axial load, rotary load and moment load.

2.Open Angular Contact Ball Bearing (KA, KB, KC, KD, KF, KG series)
Thin-section angular contact bearings are designed for supporting axial load .They can also used to support radial or combining radial traction .But this type can’t solely used to sustain moment load or reverse radical forces. They always appeared in pairs.

3.Open Four Point Ball Bearing (KA, KB, KC, KD, KF, KG series)
Thin-section four-point contact bearing is the ideal choice for supporting moment heavy pressure. It successfully satisfies the four points contact between raceway and steel ball in order to support moment load and reversing axial load. Although it can be applied in light load.

4.Sealed Radial Contact Ball Bearing (JHA, JA, JB, JU. JG series)
Thin-section sealed radial contact ball bearing design for mounting shaped ring both sides on the basis of thin-section radial contact bearing. This perfect structure can impetus the protection function, maintain the internal cleaning of bearing and efficient lubricant. But the rotary number of the comparative open or with isolation block of bearing is low.

5.Sealed Four Point Contact Ball Bearing (JHA, JA, JB, JU. JG series)
Thin-section sealed four-point contact ball bearing is also designed for mounting shaped ring both sides on the basis of thin-section four-point contact ball bearing .We have many options for the structural form of the shaped device. Others performance are the same with thin-section four-point contact bearing, except for the low rotational speed.
